NCP5050MTTXG

Overview

The NCP5050MTTXG is a high-efficiency DC-DC boost regulator from onsemi, designed for LED driver applications. It operates with an output voltage up to 20V and delivers a switch current of 3A. The device utilizes a fixed switching frequency of 1950kHz to minimize external component size. Packaged in a compact 10-WDFN (3x3) footprint, it supports PWM dimming control for precise brightness adjustment. This integrated solution combines the controller and power MOSFETs into a single surface-mount device.

Feature Summary

Integrates current-mode control architecture with internal power switches
Supports pulse-width modulation (PWM) dimming for accurate light intensity control
Utilizes high-frequency operation to reduce passive component requirements

Applications

Backlight drivers for mobile devices and displays
Camera flash LED drivers
General-purpose step-up voltage regulation for portable electronics

Procurement Notes

Verify the specific suffix MT against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with required thermal dissipation standards for the WDFN-10 form factor. Cross-reference RoHS compliance status directly with manufacturer documentation prior to integration.

Selection Notes

Select this component when a compact solution for driving high-current LEDs is required. The fixed 1950kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 3A switch current limit for load requirements and ensure input voltage ranges align with system battery or supply characteristics.

Part Context

This part belongs to onsemi's portfolio of analog and mixed-signal power management integrated circuits. It falls under the category of switching regulators specifically optimized for LED lighting applications. The series provides solutions for portable consumer electronics requiring efficient power conversion in minimal space.
